STANDARD OPERATION
Operation of makeup or breakout of a joint is as follows:
1. Ensure the Backup and Tong jaws are in the open position.
2. Position the Backup and Tong onto the tubular. Ensure the tubular comes to rest on the back
jaw of the Backup.
3. From the Backup control on the Tong, close the arms until the jaws make contact with the
tubular. Hold the control for about 1
– 2 seconds so that the pressure is allowed to build up to
the desired reading before releasing.
4. Engage the Tong jaws onto the tubular and makeup or breakout the joint. If tightening the
threads, on the last turn it is recommended to have the Tong in low speed to reduce any
sudden shock loads on the unit from stops when the threading is fully engaged. If loosening
threads, the torque should be built up smoothly on the Tong avoiding
“jerks” of the control
handle to
try to “snap” apart the joint.
WARNING: Sudden shocks on the unit as a resu
lt of trying to “snap” apart a joint may
result in shock loading on the Backup pins and lead to premature wear or
damage.
5. Release the Tong jaws first and then the Backup jaws.
6. Move the Tong and Backup off the tubular.

COLD WEATHER OR ENVIRONMENT OPERATION
If the unit is to be operated in cold weather or environments, the following considerations and
precautions should be taken into account:
1. Lubrication grease needs to be compatible with the temperatures and environment of operation.
Ensure to grease when the unit is free of moisture or condensation.
2. Hydraulic fluid should also be compatible with the temperatures and environment of operation.
3. Always allow the unit to run free for at least 15 minutes to allow hydraulic oil and lubrication to
warm up.
4. In extreme low temperatures, many components of the unit may be susceptible to brittle failures
and therefore care is required in running the unit to avoid sudden or shock loading which may
lead to failure or breakage.
5. The seals of the hydraulic cylinder of the Backup have an approximate operating minimum
temperate of -35
°C
(-31
°F
) and should be good for majority of applications. If colder and harsh
conditions are to be operated in, then consideration should be given to seals that can handle the
environment.
